Application filed June 24,

To all to 7mm may concern Beit known that l, AN'roN Rosn (changed by court order from Anton lduzicra a citizen of the United States, and a resident of Cleveland, countylo't' Cuyahoga, and State oi. Ohio, have invented anew and usetul Improvement 'iir Snap Fasteners, of which the followingis specification, the principle of the invention being herein explained and the bGSb'JIlOClG in which I have contemplated applying that principle, so as to distinguish it wtrom other inventions.

The type of fastening device to which the present improvements relate is also known as a press stud and is largely used in place of buttons for fastening garments or similar materials together. The present improved construction of snap iiastener or press stud is designed more especially in situations where consii'lerable strains have to be resisted, as for instance, on automobile curtains, hand bags, suit cases, sample cases, portfolios and pocket flaps, such, for example, as are found on such cases, portfolios and on the doors of automobiles. Not only do the parts of the fastener, where designed for such use as those ust indicated, require to be of substantial construction, but instead of being sewed on, as in the :ase of ordinary garment fasteners, they are secured in place on the fabric by means oi? washers, through which the body portion oi the iastcner 1 art"passes and is then upset. In order to prevent the material from pulling: away from these washers, they are usually formed with prongs,or equivalent projections, that bite into the material,

but this has not been foundv at all. satisfactory since the material will in turn pull away 't'rom such prongs.

The object oi the present invention, according v, is to provide a method (it attaching the snap Fastener parts to fabric 1naterial which will obviate the difficulty just lll fllCil Jeti, so a not only to assure permanency oiattachment, but also a neat appearance seas to re dar devices of the general class in hand satu. artery for use in a number oi situations where they are not at present employed.

To the accomplishment of the foregoing and related ends, said invention, then, con- 1921. Serial No. 480,008.

a bottom plan view of such female member by itsell previous to attachment; Fig. 3 is a similar plan viewof a memberthat-cooperates with said female member when attached; Fig. 4 is a broken perspective View of a portion of said last-named member; Fig. 5 is a side elevation ot one oi? the componentparts of the male member of the device; and Fig. 6 is a similar View oiianother part of such male inemliiero In their general construction both the principal members composing; the device are of familiar construction. Thus'the female or socket member, shown-in Figs; 1 and Q, is-in the term ota disk-like base '1 from: the center of which rises a tubular projection 2. The periphery of the base is rolled overto form a flange 3, by JTWRHS OfWlIlClI a spring 4- is he d inplace in, said. base. Such spring con'iprises abody portionof approxiinately semi-circular 'll'OlDlEUlfl two shaped terminal portions so disposed that the free ends o lie pair-allel and intersect suitable slots 9 'in thesidesof the tubular extension 2. Y

Ordinarilythe member justdescribed is secured to the sheet'offabric, or like article, by inserting tubular extension 2, through an aperture in such fa'liirio andthen through ile .i'asher that is pressed against the oppo e side of such fabric from thebase l. of the member by rrimping or rolling down the edge of such extension, Such washer, as previously indicatem-is usually provided with teeth or equivalent gripping elements that bite into the material with the object of preventing it from being pulled away from between the washer and the opposed base 1.

In my present improved construction I employ a washer 10 of the cross-sectional. form shown in Fig 1, from Which it will he seen that such washer is provided with Hanger; l1 and 12 adjacent its inner and outer edges, respectively, such outer flange being formed by rolling in the periphery of the *asher, thereby affording a relatively broad contacting surface that is opposed'to the rolled in flange 3 of base 1. Furthermore, in the annular space between the flanges 11 and 12 I seat, a supplemental washer 13 which is formed with a series of upstanding prongs or teeth 14, preferably formed by stamping a series of holes through the washer and leaving the sharp edges project. These prongs or teeth will be forced into the material at points lying betwcen'the co-acting flanges of the base land washer 10, and the hole in the material through which tubular extension 2 passes. Accordingly, the material. is doubly secured against withdrawal from between the two main elements composing the socket member. In the first place it is tightly gripped between the opposed flanges 3 and 12, andin the second place the supplemental washer 18 serves to hold the material from being pulled radially away from the hole through which the extension 2 passes.

The male or stud member, as shown in Figs. 1, 5 and 6, compriseain the first place. an outer sleeve 15 flanged at its base and having its head larger than its body portion so as to enter between and be engaged by the spring ends 5 when the two parts of the device, are brought together. In the second place said member comprises a tubular rivet 16 having a head adapted to oppose the base of member 15, and a stem that enters the body of said member, and is there upset, whereby the two are securely fastened together. In so far as the elements just described are concerned, the construction is that familiarly employed, but, in addition, I

here utilize again a sup 'ilement-ary washer 17 that, in its construction and function, is exactly the same as that of washer 13, said washer, 17 being preferably inserted between the head of the rivet and the material, although, if desired, it could be placed between the base of the member 15 just as well. 7

' Other modes of a iplying the [Hll'lCiplG of my invention may be employed instead. of the one explained, change being n'iade as re gards the mechanism herein disclosed, pi:ovided the means stated by any of the following claims or the equivalent ofv such stated means be employed.

I therefore particularly point out and dis tinctly claim as my invention 1. In a device of the character described, the combination of a member comprising a base and an extension adapted to pass through an aperture in a sheet of material to which such device is attached, a second i'neni ber adapted. to be secured to such extension, said member being formed with a peripheral flange disposed to press against such sheet of material, and a washer lying within such flange and formed with teeth adapter. to grip such sheet.

2. In a device of the character described, the combination of a member comprising a peripherally flanged disk-likebase and tubular extension adapted to pass through an aperture in a sheet of material to which such device is attached, a second annular member adapted to be secured to such extension, said member being formed with a peripheral flange opposed to the flange in said first member, and a washer lying within such flange on said second member and formed with teeth adapted to grip such sheet.

3. In a device of the character described the combination of a member comprising a base having an annular outer flange and a tubular extension adapted to pass through an aperture in a sheet of material to which such device is attached a second member adapted to be secured to such extension and having a peripheral flange adapted to press against such material in annular alignment with said'flange on said base, said flange on said second member forn'iing an annular space, and a washer. adapted to be received in such annular space and provided with teeth adapted to grip such material.

4.. In a device of the character described, the combination of a member comprising a base having an annular outer flange formed by rolling the outer edge to form a curved, non cutting edge, and a tubular extension adapted to pass through an aperture in a sheet of material to which such device is attached, a second member adapted to be se-- day of dune, 19:21.
